Natural pox infection occurred in a free-living rough-legged hawk (Buteo lagopus) in northeastern North Dakota. Gross, histological and electron microscopic findings were typical of pox infection, and characteristic lesions developed in red-tailed hawks (Buteo jamaicensis) but not in great horned owls (Bubo virginianus) following inoculation with case material. Death of the rough-legged hawk was attributed to starvation rsulting from inability to capture prey and to blood loss from foot lesions.
在北达科他州东北部一只自由放养的矛隼（Buteo lagopus）身上发生了自然痘感染。大体、组织学和电子显微镜检查结果均为痘感染的典型表现，用病例材料接种后，红尾鹰（Buteo jamaicensis）出现了特征性病变，但大角鸮（Bubo virginianus）未出现。矛隼的死亡归因于无法捕获猎物导致的饥饿以及足部病变引起的失血。
